Intra-articular Treatment with Triamcinolone Hexacetonide Associated with Gold Nanoparticles Reduces Cartilage Degeneration in an Animal Model of Osteoarthritis.

Introduction: The association between triamcinolone hexacetonide (TH) and gold nanoparticles (GNPs) represents a promising treatment due to the potential anti-inflammatory and antioxidant effects of these compounds. In this study, we evaluated the effects of intra-articular treatment of TH associated with GNPs in a mechanical model of osteoarthritis (OA).

Methods: Fifty Wistar rats were divided into five groups: Sham; OA; OA+TH; OA+GNPs; OA+TH-GNPs.

Treating psoriatic arthritis to target: discordance between physicians and patients' assessment, non-adherence, and restricted access to drugs precluded therapy escalation in a real-world cohort.

The treat-to-target strategy (T2T) was associated with better outcomes in psoriatic arthritis (PsA) compared to standard care in clinical trials. This study aimed to analyze factors precluding treatment optimization in a T2T strategy conducted in a real-world cohort of PsA patients. A retrospective cross-sectional study nested in a cohort was conducted.
